i have a silverstreak in 20 cal. it will take out a pigeon easily but you miss a lot because of the noisy pumping. my other air rifle is the ultimate hunter. diana 34 in .177 k illed many pigeons . it shoots 177 pellets over 900 fps and virtully no holdover out to35-40 yards. i had .22 and 177 models. sold the .22 too loopy trejectory . the 177 does enough damage due to the speed of the pellet to take out g hogs at 30 yards. i got 4 that were burrowing under the porch at work- all 1 shot kills with iron sights head shots.
